The Ballarat Battery Energy Storage System (BESS), currently in the final testing phase, is the first facility of its kind in the state. Owned by AusNet Services and operated by EnergyAustralia, the facility is capable of powering more than 20,000 homes for an hour of critical peak demand before being recharged. It is located at AusNet Services' Ballarat terminal substation.

A consortium led by Downer Spotless completed the battery system with technology provider Fluence serving as a supplier.
